What is ESG software?

ESG software is a digital platform used to collect, organize, analyze and report environmental, social and governance data.

Depending on the platform, it can support:

• preparation of a sustainability report;

• reporting aligned with CSRD, ESRS, GRI and VSME;

• corporate carbon footprint calculation;

• monitoring of Scope 1, 2 and 3 emissions;

• collection of data and evidence from suppliers;

• product carbon footprint and Life Cycle Assessment;

• ESG KPI and performance tracking;

• materiality and risk assessments;

• audit and certification workflows;

• disclosure and compliance management.

The best ESG reporting software should help manage the data behind the final report. This includes identifying data owners, collecting evidence, monitoring progress and keeping a traceable record of changes and approvals.

Without this structure, companies may produce a report while continuing to manage the underlying information through disconnected spreadsheets, emails and folders.

ESG software becomes particularly important when an organization operates across several countries, sites or legal entities. International teams need a shared environment in which local contributors can provide data while central sustainability teams maintain common methodologies, standards and controls.

How to choose the best ESG software in 2026

There is no platform that is right for every organization. The best ESG software depends on the company’s reporting obligations, operational complexity and sustainability priorities.

A global manufacturing group collecting data from sites, products and suppliers will have different requirements from a listed company focused on financial and sustainability disclosure. A company looking mainly for climate tracking may prefer a specialized carbon accounting tool.

Before comparing platforms, consider the following areas.

Start from the processes you need to manage

The first question is what the software must help your company accomplish.

Some organizations need ESG reporting software to prepare disclosures aligned with CSRD, ESRS, GRI or VSME. Others begin with carbon accounting across Scope 1, 2 and 3. Industrial companies may also need product LCA, energy data, supplier assessments or workflows for certifications and regulatory compliance.

A platform should cover the immediate priority while giving the company room to expand. An organization starting with sustainability reporting may later need to add Scope 3, product environmental data or supply chain assessments.

Check how the platform collects data

Most ESG work takes place before the final report is generated.

The platform should make it possible to:

• assign responsibilities to specific data owners;

• collect information from different departments and sites;

• import documents, spreadsheets and system data;

• connect every figure to a source;

• track missing or incomplete information;

• review changes and approvals;

• reuse data across different reports and calculations.

This is particularly important for international companies, where data may be collected in different languages, units and formats.

Look for audit-ready traceability

The best ESG audit management software should create a clear connection between each reported figure and the supporting evidence.

Useful capabilities include:

• documented sources;

• calculation methodologies;

• version histories;

• approval workflows;

• user permissions;

• audit trails;

• dedicated access for auditors and external reviewers;

• corrective action and compliance tracking.

Audit readiness matters for regulated disclosures, voluntary reports, carbon footprint verification and certification processes.

Evaluate materiality and risk management

Materiality assessment is central to many ESG reporting processes. For companies subject to the CSRD, this includes assessing both impacts and financial risks and opportunities.

The best software for ESG materiality assessment should help companies:

• identify relevant sustainability topics;

• engage internal and external stakeholders;

• score impacts, risks and opportunities;

• document methodologies and decisions;

• connect material topics to disclosures, KPIs and actions;

• update the assessment as the business changes.

Risk identification should also extend beyond the final materiality matrix. Companies may need to map supplier risks, regulatory exposure, climate risks and gaps in policies or performance.

Verify the reporting frameworks available

A strong ESG disclosure management platform should not lock the company into one framework.

Depending on its size, geography and stakeholders, an organization may need to work with:

• CSRD and ESRS;

• GRI;

• VSME;

• ISSB standards;

• CDP;

• customer questionnaires;

• internal ESG frameworks;

• sector-specific disclosure requirements.

The ability to reuse the same data across several frameworks reduces duplicated work and improves consistency.

Consider performance tracking and automation

ESG management continues after the report has been published.

The best ESG performance tracking software should help teams monitor KPIs, identify gaps and compare progress across sites, entities or reporting periods.

Dashboards and automated workflows can support:

• recurring data collection;

• reminders and task management;

• year-on-year comparison;

• target monitoring;

• gap analysis;

• hotspot identification;

• action plan management.

AI can also support document extraction, data classification and questionnaire completion. The company should still be able to review sources, methodologies and outputs.

Top 3 best ESG software platforms in 2026

The three platforms in this comparison cover different areas of the ESG software market.

1. Metrikflow: best all-in-one ESG software for international industrial companies

Metrikflow is an AI-powered ESG management platform designed to centralize sustainability data, workflows and responsibilities.

It is particularly suited to international industrial companies, multi-site organizations and groups that need to coordinate information across operational sites, legal entities, products and global supply chains.

The platform supports:
